So, $BP.L, the oil company that destroyed the ocean, has seen their stock tank, down over $250 from it's year high.  Is it a good buy?  Probably.  Once they get the gulf cleaned up and pay everyone off, they'll continue to make more money than they can count.  The question is, do you want to support a company that has done shitty stuff?  I for one don't, but that's my person opinion.  I also don't buy Alcohol or Tobacco companies because I don't drink or smoke and think both are a huge waste of peoples time and money and health, but again, that's just me.  I also don't short stocks because I don't want to bet against people who are having a rough time. 

With all that said, is BP.L a good buy?  I would say it probably is and if you have enough money to buy a large quantity of shares, you could make a bundle, but at $405 a share, it has the same problem Google ($GOOG) has, which is you can't buy enough shares to make the large jumps it makes worth the risk.  If you bought 10 shares, that's $4050, even if it goes up $200, you made $2000.  Not a bad payout, but do you want to risk $4050 to possibly make $2000?  Not so sure.  For $4050 you could buy 120 shares of Disney and it would only have to go up to $50.41 to get the same profit, AND you'd have less risk, AND you'd be able to sell some shares to grab out profit and lower your taxes on the gains.  So, I wouldn't do it, but that doesn't mean you shouldn't.

Invest in peace...
